The reduced radius of the upper and lower body gives the Cat 303 mini excavator stability and maneuverability in a compact machine. 303 Cat excavators provide exceptional stability in a small package. The upper body is always within the width of the undercarriage, so there is no tail swing and you can work in tight spaces with confidence.Cat 303 Review
